IMPROVEMENT IN DRdPPEl2S FOR REAPlNG-MACHINES.

Specification forming part of Letters Patent No. 173,970, dated February 22, 1876; application filed December 21, 1875.

To all whom it may concern:

Be it known that I, WILLIAM B. KREIGH- BAUM, of Green township, Summit county, Ohio, have invented an Improvement in Droppers for Reaping-Machines, of which the following is a specification My invention relates to that class of reaping-machine droppers 'wherein a series of slats proj ct at right angles from a shaft or bar hinged parallel. to and at the back of the cutter-bar, against Which slats, inclined upward by means of the shaft or bar, the cut grain lodges until sufficient has accumulated thereon to form a gavel, when the slats are dropped, allowing the stubble to push the gavel 01f onto the ground.

The object of myinvention is to divide this gavel from the falling grain and even the butts thereof as it is dropped; and I accomplish this by means of a narrow board, lying directly back of the knives upon a narrow platform on top of the cutter-bar and droppershaft, arranged to revolve upon its rear edge as thegavel is dropped until it stands perpendicularly, and return to its former position by the lower edge sliding along the narrow platform to the front. g

In the accompanying drawing, Figure 1 is a perspective view of the cutter-bar, dropper, and attachments, embodying my invention; Fig. 2, a cross-section of the same at the point :v :r, showing an elevation of the end-board It; and Fig.3, an end view of the same, looking from the machine.

O is the cutterbar, on which it.was not deemed necessary to show the fingerguard, at the back of which is hinged the dropper-shaft D, with projecting slats s s, and moved by the lever L, connectunder the platform P, is a shaft, F, parallel to the cutter-bar, properly journaled at each end to revolve freely, and having fastened thereto the arm G and forked arm H, (see Fig. 3,) and the board A is journaled between the ends of these arms by the pins E E. To one fork of the arm H is attached the connecting-rod O, also attached to the lever L. Between the arm H and board A is the upright endboard It, provided with the curved slot Q, and on the face of which are raised fillets or ridges r r t t and gravitating catches, V Z. On the end of the board A nearest the machine are the two short pins '5 i, so arranged as to pass freely over the face of the board R but be arrested. by the ridges 1' r t t and catches V Z.

In operation, the board A lies in the position shown in Fig. 1, the dropper raised. When it is desired to drop the gavel, the lever L is drawn back, dropping the slats s s to the ground, by means of the rod M and arm N. At the same time the shaft F is revolved, raising the board A by the pins E E and arms G H; but the pin '5, meeting the form P, and under any grain that has fallen thereon, while the pin 11 passes down between the fillets t t past the catch Z.

H aving' thus described my invention, I claim 1. The board A, platform P, shaft F, arms G H, and end-board R, all operating substantially as shown, in combination with the cutter-bar O and dropper D, for the purposes hereinbeforc stated.

2. Theiboard A, having the pins 13 i, in combination with the end-board R,provided with the ridges r r and gravitating catches Z V, substantially as described.
